ALR0688E The Link Quality Percentage of port port_name in device device_name was found to be measured_value, which violated the defined critical-stress boundary value of boundary_value.
Explanation
Link Quality Percentage estimates the relative quality of the connection of a switch port. The percentage is based on whether the port is an expansion port (E_port) or a fabric port (F_port), and on the numbers and types of errors that are detected by the port. A threshold is defined on this metric, which can be used to compare the value of the Link Quality Percentage with the defined boundaries for each set of performance statistics collected from the switch.
A threshold boundary violation occurred. The specified switch port has a Link Quality Percentage value that is less than or equal to the critical-stress boundary defined for the related threshold.
The threshold violation may indicate that a hardware or configuration problem exists either for this port or for the connected port or cable. Isolated errors can generally be ignored, but if the percentage remains consistently high, the errors may be a cause for concern.
Action
Contact your resource vendor for troubleshooting guidelines for the switch, and for the connected resource (storage system, switch, or server HBA).
Because isolated temporary errors can generally be ignored, consider enabling the alert suppression option "Suppress alerts unless the triggering condition has been violated continuously for a specified length of time" for this threshold. This can reduce the number of unnecessary alerts.
